Electropolishing Services
Electropolishing enhances the corrosion resistance of metal by removing impurities and creating a clean, passive surface.
introduction
Clean Surface with Electropolishing
We smooth out surface irregularities, resulting in a polished and reflective finish while also removing burrs and sharp edges.
DEK's electropolishing process can reduce residual stresses in the metal, improving mechanical properties and fatigue resistance. Electropolishing forms a protective oxide layer, contributing to passivation and increased durability. Furthermore, the process aids in maintaining cleanliness, hygiene, and ease of cleaning. We have a team of experts who is knowledgeable in the intricacies of the process, ensuring the efficient removal of impurities, burrs, and surface irregularities. This expertise extends to achieving specific surface finish requirements with a keen eye for detail. Moreover, DEK focuses on customer satisfaction by offering personalized solutions. Our company is adaptable and can meet various needs and specifications, providing customized electropolishing services to match individual project requirements.
TECHNOLOGY OVERVIEW
More About Electropolishing
What’s Electropolishing?
Electropolishing is an electrochemical method used to enhance the surface quality of metals, most commonly stainless steel. In this process, metal workpieces are immersed in an electrolyte bath alongside a cathode, and an electric current is applied. This causes a controlled removal of a thin layer of metal from the surface, effectively smoothing out imperfections like scratches and burrs. Electropolishing is known for creating a highly reflective and aesthetically pleasing surface finish, often resembling a mirror. Additionally, the process can improve corrosion resistance by inducing the formation of a protective oxide layer on the metal.

Design Considerations for Electropolishing
- Choose metals suitable for electropolishing, like stainless steel or aluminum.
- Clearly define the desired smoothness and shine.
- Design parts with accessible surfaces for even polishing.
- Protect areas not to be polished and ensure proper contact points.
- Consider material thickness to avoid structural issues.
- Adjust for potential rounding of edges during electropolishing.
- Ensure surfaces are free from contaminants.
- Design secure fixtures for even exposure to electrolyte solution.
- Choose the appropriate electrolyte for the metal being polished.
- Control current density for even polishing.
- Consider additional treatments or coatings.
- Adhere to environmental regulations for waste disposal.
- Implement inspections for specified requirements.
FAQ
Electropolishing FAQ
Electropolishing typically involves using an electrolyte solution, often a mixture of sulfuric acid and phosphoric acid. The specific chemical composition can vary depending on the electropolished material and the desired finish.
The hazards associated with electropolishing primarily stem from the use of corrosive chemicals. Sulfuric acid and phosphoric acid, commonly used in electropolishing, can pose risks such as chemical burns, inhalation hazards, and environmental concerns.
Electropolishing effectively removes surface contaminants from stainless steel and other metals, including rust. Removing oxides and impurities can improve the material's corrosion resistance, leaving behind a smooth and polished surface.
Electropolished surfaces typically exhibit a smooth, shiny, and reflective appearance. The process removes surface irregularities, burrs, and contaminants, resulting in a polished finish. A visual inspection and knowledge of the material's specifications can help determine if something has undergone electropolishing.
Yes, electropolished stainless steel is considered food-safe. The electropolishing process removes impurities and contaminants from the surface, enhancing the corrosion resistance of the stainless steel.
